Petr Hosek 0ba22f51d1 [builtins] Use single line C++/C99 comment style
Use the uniform single line C++/99 style for code comments.

This is part of the cleanup proposed in "[RFC] compiler-rt builtins
cleanup and refactoring".

Chandler Carruth 57b08b0944 Update more file headers across all of the LLVM projects in the monorepo
to reflect the new license. These used slightly different spellings that
defeated my regular expressions.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Chris Bieneman d470f434ab Delete remaining compiler-rt makefiles
Summary:
Since we can now build the builtins without a full toolchain these files should no longer be needed.

This is the last vestige of autoconf!

Saleem Abdulrasool 590e85b575 builtins: tag with noexecstack
These routines do not require executable stacks.  However, by default ELFish
linkers may assume an executable stack on GNUish environments (and some non-GNU
ones too!).  The GNU extension to add a note to indicate a non-executable stack
is honoured by these environments to mark the stack as non-executable (the
compiler normally emits this directive on appropriate targets whenever
possible).  This allows normal builds from getting executable stacks due to
linking to the compiler rt builtins.

Martell Malone 40eb83ba56 Support for 32-bit mingw-w64 in compiler-rt.
Add chkstk/alloca for gcc objects.
Replace or instructions with test, the latter should be marginally more
efficent, as it does not write to memory.

Saleem Abdulrasool 1fe0c18914 builtins: cleanup constant data section selection
Each of the object formats use a different directive for selecting the constant
section.  Use a macro to avoid the duplication across a number of files.  Also
correct a small macro mismatch on the Windows case (HIDDEN_DIRECTIVE -> HIDDEN).

Saleem Abdulrasool 24c68b26d8 builtins: add missed files from previous commits
This adds missed files in SVN r214033 for alignment and corrects a change from
SVN r214034 for fixing compilation with GCC.

Saleem Abdulrasool 93efc78a04 builtins: make the x86_64 compatible with GAS
The .rodata directive was added on the IA-64 (Itanium) platform.  The LLVM IAS
supports the .rodata on i386 and x86_64 as well.  There is no reason to really
restrict compilation of the builtins to just clang.  By explicitly indicating
that the data is meant to be pushed into the .rodata section via the .section
.rodata, the assembly is made compatible with clang and gcc (with GAS).

This will enable building these routines on the Linux buildbots via CMake.

Saleem Abdulrasool 2fd910dc72 compiler-rt: prefer .rodata for non MachO targets
Place constants into .rdata if targeting ELF or COFF/PE.  This should be
functionally identical, however, the data would be placed into a different
section.  This is purely a cleanup change.

Saleem Abdulrasool 57aa97f53a compiler-rt: whitespace and uniformity for arm
Make the whitespace a bit more uniform in the various assembly routines.  This
also makes the assembly files a bit more uniform on the ARM side by explicitly
stating that it is using the unified syntax and that the contents of the code is
in the text section (or segment).  No functional change.

Saleem Abdulrasool 310874ae3c [CompilerRT] use .p2align, .balign instead of .align
The .align statements in ARM assembly routines is actually meant to be a power
of 2 alignment (e.g. .align 2 == 4 byte alignment, not 2).  Switch to using
.p2align.  .p2align is guaranteed to be a power-of-two alignment always and much
more explicit.

The .align in the case of x86_64 is byte alignment, use .balign instead of
.align.
